Paul, 5 GHz works NLOS in an urban environment. Bouncing around buildings, etc. Look at the success of Redline and Orthogon. OFDM and 5 GHz works well for them. An environment with trees is different. Trees absorb the signals, instead of bouncing them. Especially wet trees!
We utilize 2.4 at every pop, mainly because of the low cost for deployment, and general coverage. We utilize 5 GHz frequently and also 900 MHz for NLOS issues. I hope this helps Mike -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paul Hendry Sent: Tuesday, January 03, 2006 4:44 AM To: 'WISPA General List' Subject: [WISPA] 2.4GHz vs 5GHz Ola everybody, I hope everyone had a great Christmas and New Year and are all ready for 2006, the year of the WISP :) When I have setup wireless in an area it has always depended on the Geographic's of the area as to if we deploy 2.4GHz or 5GHz and I have always decided that 2.4 should be used where NLOS could be an issue. This decision has always been based on the fact that the lower frequency will pass through trees a lot easier however I have recently read a white paper that suggests otherwise. Basically the document says that the higher the frequency, the better the scatter (the ability to bounce of and around objects). It also says that 5GHz is better at penetrating walls. So my question is, have I been basing some of our deployments on false information or am I missing something here? I know that in tests I have seen a more stable signal at 2.4GHz in a NLOS environment but is this just a fluke? Cheers, P. -- No virus found in this outgoing message. Checked by AVG Free Edition.
